Is Dr. Strange a Skrull now? I think so. He was taken just after the skurll broke free of the crimson bands, the panel where his face is distorted. Also I find the cover disturbing, strange is the largest hero on the cover and he's looking straight at the reader. It would make sense also to have Strange as a skurll, so he could spy on the new avengers, since they were the ones to discover the invasion.
